In Chicago, we have a PHENOMENAL deli on the northwest side of the city called Andi's Deli (http://www.andysdeli.net/). They are predominantly a Polish deli, but they have other European offerings, including the thick-skinned German-style veal hot dogs that my mother used to prepare for us when I was a kid (by the way: this type of hot dog is gluten free). They are still one of her favorite foods, and since she and my dad are visiting today, I thought I'd surprise her.
